, Application filed Ja eiso, 1924'. Serial 170,723,387.

To allwhomz'tmay concern: Be it known that I, IEARLE R. EvAns, a citizenof the United .States, residing at Gottageville, in the county ofJackson and State of WVestVirginia, have inventednew and usefulImprovements in Wall-Building Machines, of which the following is aspecification. 1 j c V My present invention has reference to a devicefor facilitating the-erection of walls of buildings. 3 In carrying outmy invention it; is my purpose to. erect a scaffold comprising;adjustable sections and having-ascaifold board or platform thereon, thesaid scaffold hav ing adj ustably: secured thereon a carriage havingmeans for supporting. thereon with the outer surface of a. wall in thecourse of erection, the, said plumb board.

having associated therewith a right angularly disposed longitudinally-fmovable scraper whereby the mortar between the.

courses of brick, stone :or the like maybe 'properly scrapedandvmeasured, and :also

' whereby the top of a. concrete wallmay be are designed to haveremovably, secured to likewise scraped or-leveled. I

l/Vith theabove broadly stated view, many others 'will appearas thenature of the invention is betterunderstood,reference is to be had tothe drawingswhich accompanying and which. form/part of this application.7

In the drawings Figure 1 is an end'view ment. y v

Figure 2 is a top planview thereof.

Figure 3-is a'sectional 7 view on the line 33 of Figure 1.

of the, improveouter face'of the plumb board.=

Figure 5 is a sectional View onthe line 55 of Figure v i I As disclosedby the drawings I- secure on suitable base plates lthe lower tubularsections 2 of a scaffold. The sections 2 are .arranged in spaced pairson each base 1 and the upper ends thereof similar tubular members 3providing scaffold extensions.;Any

v 'desired number of suchextensionsmay be employed, and the uppermostextensions are connected together by a bar 4 having socket ends 5through which pass threaded plugs 6' projecting from'the outer ends ofall of the objects'in Figure 4 is a View looking toward the y 1 turnbuckle 24:. The outer end of this rod sections. by nuts 7.

so'cket end 9 through which the said corner posts pass, and each of thesockets is pro- .The threaded plugs are engaged vided with a bindingelement 10 for bold ,ing the bars S' adjustably' secured'on thescaffold. The bars 8 are designed to support thereon a scaffold board llupon which the operator stands.

. S lidably arranged on the corner posts of the scaffold thereisa'carriage12, the same 3 preferably comprising upper and lowertransverse bars having socketplates carrying binding means'13 forengaging the corner fipostsof the scaffold. The. upper and plumb 1 boardfor, contacting engagement lowerbarsiateach endof the scaffold areconnected togetherby a spider 14, and jourthere is a shaft 15 carryingadrum around which is wound a flexible element'or cable 16. The cable 16has one end secured to a sheave block 17, supported. from the upperconnecting. bar l, the cable being likewise [trained around the pulley'in the sheave block and hasits free end wrapped; around acleat 18., Thefree end of the" cable. is

within the reach of the operator on the board orlplatform' 11, and inorder to more effectively sustain the carriage adjusted "on the.platform, I secure on the shaft 15 a ratchet wheel 19 normally engagedby a dog a 20 whichis pivotally supportedin the carriage,

The socket members of the carriage on v the posts of the scaffold nextto the wall 21 are provided with outstanding ears- 22 and 23, and totheupper ear there is pivoted a sectional rod whose ends are engaged by ais pivoted as at 25 to a bar 26. that has its inner end pivoted totheears 23.

Secured by removable means 27 approximately central. on the under facesof the 7 bars 26 thereis arail 28, preferably hollow and ofsubstantially rectangular formation. Beneath the rail '28 there areplates 29 and brackets indicated 'by the numeral 34; are

extended downwardly, and between the arms :33 and 34 there is a suitablebrace 35. V

The "anglebracketshave their... arms ii l hingedly secured to plates36'ith'atriare screwed ion or otherwise fe'lfectiyely'secured totheouter'face of:aplumbgboaird37;"(The pl'ates36 also carryoutstandingthreaded 1 studs 38 that pass throughi'suitable LQPBII- vinays in the arms '34,. and the said studsare engaged by outer wingednuts-39" and" inner nuts lO. i

By an' arrangement as above described :it

be sustained in proper" VQI flZl'CQJl pOSltiOD' by the adjustment ofithenuts 39 and "40 and the turn buckle 2d. 111 will be further notedthat the plumb iboard, through the adjustment of the-'yangle bracketswith respect to the p 2 may be 'prQpeflrfpQ against the outer face Vof'fthe wall? 21, fa-nd likewise that" the plumb-"board 37tmay"'be= m v lngitud nallyi" th ilenst 1 dfrthe seaflold, overithe outer faceoftthewall. 21.

The }guideshaye their inner, faces centrally andlongitirdinal-,ly slotted, as at 4'3.

With my construction it"will be apparent= that a wallmay beerected moreexpeditiously and witha' less amount ofglabonthan is usually'required,"-and while I- believe thatthe foregoing description, -whentaken in I connection with i the drawings will fully set forth theconstruction, advantages and op- 1,545,1asa
